DNA identification analysis, identity testing, profiling, fingerprinting, typing, or genotyping refers to the characterization of one or more relatively rare features of an individuals’s genome or hereditary makeup. Every human, lower animal, and sexually reproduced plant has a characteristic phenotype or physical appearance because each possesses a unique hereditary composition. The exception to this rule is identical twins, who possess the same unique genotype but, owing to the consequences of complex developmental events, have subtly different phenotypes. The DNA of any individual is identical whether it is extracted from hair bulbs, white blood cells, or a semen specimen. These principles of individual uniqueness and identical DNA structure within all tissues of the same body provide the basis for DNA profiling.
